Unified Extensible Firmware Interface (UEFI) is designed to replace the BIOS. UEFI is a standard firmware interface which controls the booting process of the system and passes the control to the OS.
The traditional method to enter the BIOS/UEFI is to press the F2 or Fn+F2 keys. This method often fails when the system boots faster.
Note: The keys may vary according to the manufacturers.
Press Shift key while restarting the system.
You will be directed to the blue boot options menu.

Now you will be getting a blue boot options menu. Follow the same steps as that in method 2 to access the UEFI/BIOS.
